Title (EN) FUEL NOZZLE CHECK DAMPER
(FR) AMORTISSEUR DE CONTROLE D"UNE BUSE DE COMBUSTIBLE
Abstract: front page image
(EN)A fuel injector includes an injector body (8) having a nozzle (12), a valve seat (40) within the body (8) and closely adjacent the nozzle (12) and a valve (22) within the body (8) movable between positions seated against and spaced from the seat (40). The valve (22) is biased towards the position seated against the seat (40). Fuel is received under pressure and delivered to the valve (22). Responsive to the receipt of fuel under pressure within the body (8), the valve (22) is moved to the position spaced from the seat (40). This invention improves previously known fuel injectors by retarding the rate of movement of the valve (22) in moving from the position spaced from the seat (40) towards the position seated against the seat (40). The retarded rate of movement advantageously reduces nozzle tip breakage and associated undesirable side effects.
(FR)Un injecteur de combustible comprend un corps d"injecteur (8) ayant une buse (12), un siege de soupape (40) dans le corps (8) et adjacent a la buse (12) et une soupape (22) dans le corps (8) mobile entre des positions assise contre et espacee du siege (40). La soupape (22) est poussee vers la position assise contre le siege (40). Le combustible est recu sous pression et envoye vers la soupape (22). En reponse a la reception de combustible sous pression dans le corps (8), la soupape (22) est deplacee vers la position espacee du siege (40). Cette invention ameliore les injecteurs de combustible anterieurs en retardant la vitesse de deplacement de la soupape (22) de la position espacee du siege (40) vers la position assise contre le siege (40). La vitesse retardee de deplacement reduit de maniere avantageuse les cassures de la pointe de la buse et les effets secondaires associes indesirables.
